* To add a device support it should be BlackListed ? @ 2009-05-13 17:04 Mohamed Ikbel Boulabiar [not found] ` <45cc95260905131004x186e4ff3ga79cc943f63680d0-JsoAwUIsXosN+BqQ9rBEUg@public.gmane.org> 0 siblings, 1 reply; 2+ messages in thread From: Mohamed Ikbel Boulabiar @ 2009-05-13 17:04 UTC (permalink / raw) To: Andrew Morton; +Cc: Rafi Rubin, Greg KH, USB list, USB list Hi, I am trying with my professor Stéphane Chatty to add support to a Stantum multitouch tablet that is a HID device. We tried copying hid-ntrig.c and applying modification to get supported but we haven't reached something functional. Should we add more information to some place to reach our goals ? I have read this and we maybe need to blacklist the stantum somewhere (hid-quirks.c ?) "This patch is required for N-trig support for the Linux Environment. It requests the USBHID driver to ignore an N-trig device, when connected to the USB bus." http://kerneltrap.org/index.php?q=mailarchive/linux-usb/2009/1/20/4772014/thread Is this true ? How should we do it ? And why (because we have at least 3 to 4 other devices from other constructors and we want to add support) ?

The patch you link to was actually an ntrig employee trying to nix the existing functionality by telling the hid system to ignore the device. It is not a good positive example as to how to get hid to support your device. The first thing you should check is if IS_INPUT_APPLICATION supports the "usage" your device reports. I'm sure there's an easy way to see what usage a device reports, but I don't know about it. It's pretty easy to add a printk just before (or an else after) if (IS_INPUT_APPLICATION(col->usage)) in hid-input.c Anyway, that will tell you if the hid system is ignoring your device, and what to add to IS_INPUT_APPLICATION in include/linux/hid.h, if necessary.
